For teachers

A classroom escape game that tells you who finished, and how

Turn a revision lesson into a chain of locks, built in a spare period. Pupils play on the phones or tablets they already have, with no account. They can give their first and last name when they open the lock, you watch the class live, and every result goes to CSV.

Maths

A dozen dozen. Three digits.

Wrong answer, try again.

Eight subjects, eight locks, one escape room

Every card is a real lock, with the theme, the filmed unlock animation and the celebration a teacher can give it. Pick one to play it in the demo. In this order they make one chained story, each reveal sending the class to the next subject.

Themes, filmed unlock animations and celebrations dress any of these locks. Every lock format and every reveal, the sudoku, the Wordle and the HTML endings included, works the same way.

How does a multi-step escape room work?

A multi-step escape room is a chain of locks. Each right answer opens the next step, and the last one opens the finale. Nobody can skip ahead: step two stays shut until step one is solved, so a group always works on the same question. This is the ready-made three-subject template, exactly as a class plays it.

Step 1Numeric code (PIN)
Maths: the egg lock
The cupboard holds a dozen boxes of a dozen eggs 🥚 each.
🍳 The canteen takes one full box for a giant omelette.
How many eggs are left? 🔢 Three digits.
✓ Right answer: the class sees
Cupboard open.
The science cupboard opens.
Inside: a plant under a lamp, and a label whose word has been torn off.
Step 2Written answer
Biology: the plant's recipe
This plant 🌱 makes its own food from sunlight, water and carbon dioxide, and gives out oxygen.
🤔 What is this process called? ✏️ One word.
✓ Right answer: the class sees
Front page.
Behind the pot, an old newspaper headline:
"ONE SMALL STEP FOR MAN"
The date has been torn off.
Step 3Numeric code (PIN)
History: the torn date
The newspaper 📰 tells the story of Apollo 11 🚀 and the first human steps on the Moon.
They happened in the last year of the 1960s.
Which year? 🔢 Four digits.
✓ Right answer: the finale opens, below

The last reveal, written in HTML blocks: a headline, a ticket and a stamp, in the lock's own colours.

Three subjects, one class

The class is out.

The classroom door swings open. Every lock gave way, and you made it out together.

Well done

You can publish single locks or multi-step escape rooms, and build and preview them before paying anything. Each step keeps its own question, lock, hint, error message and reveal.

Classroom questions

What is a digital escape game for the classroom?

A short trail of locks, each one a question from the lesson. Answering opens the next, and the last one opens a box with a reward in it. Pupils play on the phones or tablets they already have, in the room, in about twenty minutes.

Do pupils need accounts?

No, and this matters for a school: pupils never sign up and never give an email address. By default nothing is stored about them beyond the anonymous progress of the browser they play on. If you turn on the option that asks for their first and last name, that name appears only in your results and your CSV export. Only the teacher has an account.

How long does it take to build one?

A five-lock trail is about twenty minutes the first time and ten after that. Start from the classroom template and change the questions.

Can I use it for several classes?

Yes. You can duplicate a game, so each class gets its own link and its own results without rebuilding it.

Can I see how they are doing while they play?

Yes: a live board shows which lock each group has reached, so you can go to the table that is stuck rather than the one that is loudest.

Is classroom use allowed?

Yes. Playing with your own class is not commercial use, which means charging people to play or building games for clients, and commercial use is included anyway. Pupils never pay and need no account.

Can my school pay for it?

Any card works at checkout, a school card included. Every payment is emailed a receipt, and invoices are on the billing page. Purchase orders are not accepted yet.

Does it work without pupil phones?

Yes. Run it on the board as a whole-class activity, or on the school tablets. One link works on anything with a browser.

Can I see which pupil finished the escape game?

Yes. Turn on the option that asks each pupil for their first and last name when they open the lock, optional or required. The names then appear in the results, next to each pupil's time, hints and tries, and in the CSV export. Pupils still need no account and no email address.

How much does it cost for a teacher?

You can build and preview a game before paying anything. Players never pay and need no account. See current plans and features on the pricing page.

What do I get to run a class?

One plan, everything included: every theme, filmed unlock animation and celebration, your logo, pupils' names, results per pupil, the CSV export, the timer, the live dashboard, the leaderboard, the QR pack and scheduling.

Can pupils cheat by replaying or changing the clock?

The timer is kept by the server, not by the phone, and each device can get one play. Add an access code so only your class gets in, and hide the steps already solved if you do not want answers read over a shoulder.

What happens to my games when my access ends?

They stop opening for your pupils, but nothing is deleted and the links do not change: they all reopen as soon as you take a week, a month or a year again. With the year, your games stay open all school year.

Your next revision lesson, as an escape game

Build it in a spare period. You will also know who finished and in how long, and with the year the game stays live all school year.
